1 Claim.

The present invention relates to time switch mechanisms and embodies,more specifically, an improved time switch mechanism wherein provisionis made for the control of suitable mechanism in accordance with apredetermined program over a period or cycle of a week. In thisconnection, it is proposed to provide a time switch control mechanismwhich is so designed that predetermined operations may be effectedduring a weekly cycle consisting of the seven week days, means beingprovided for properly adjusting the time switch mechanism forpredetermined operations on each day of the cycle, the structure beingsuch that different operations or different sequences of operations maybe efiected on the individualdays of the week.-

The present invention is a modification of the structure shown inapplicants copending application Ser. No. 577,192 filed November 25,1931 for Time switch mechanism, and an object thereof is to provide atime switch mechanism which is adapted to function on a weekly cycle. Afurther object of the invention is to provide a time switch mechanismwhich is adapted to 5 function on a weekly cycle and which is providedwith means for adjusting the operations of the mechanism as desired inpredetermined periods comprising the cycle.

A further object of the invention is to provide a time switch mechanismof the above character wherein means is provided for affording suitableadjustments and control operations on each day of a weekly cycle.

A further object of the invention is to provide 5 a mechanism of theabove character wherein the time switch mechanism functions on a weeklycycle, the cycle comprising periods corresponding to the days of theweek and the construction further being of such nature thatpredetermined and diiferent operations and sequences of operations maybe obtained for each day of the week.

Further objects, not specifically enumerated above, will be apparent asthe invention is de- 5 scribed in greater detail in connection with theaccompanying drawing, wherein:

Figure 1 is a view in front elevation, partly broken away to illustratethe driving mechanism, and showing a time switch mechanism con- 5structed in accordance with the present invention. I

Figure 2 ,is a view in rear elevation showing the driving mechanism forthe time switch of the present invention.

With reference to the above drawing, the time switch mechanism is shownas mounted upon a standard 10, this standard supporting a switchoperating arm 11 controlled by a pivoted arm 12. The arm 11 is loaded bya spring 13 and arm 12 is pivoted at 14 upon a stationary bracket 15 tomove arm 11 up and down. Arm 11 may engage and actuate a suitable camoperated switch of well known form, the right hand extremity of' arm 12,as viewed in Figure 1, serving as a manual operating arm and a left handextremity being provided with a detent 16 which is adapted to be engagedby operating lugs secured to a clock dial 17. The dial 17 ,is of annularconstruction and provided with teeth 18 upon its inner periphery.Supporting rollers 19 serve to mount the dial in a rotatable positionabout a stationary face 20. The face 20 is a portion of a clockmechanism which .actuates minute and hour hands 21 and 22, respectively,to afiford a time indicating mechanism in connection with the face 20.

Driven by the mechanism for actuating hand 30 22, is a gear 23 whichdrives a gear 24 meshed therewith. Gear24 is on a shaft common to a gear24 which drives a cooperating gear 25' which is on a shaft common to agear 25. Gear 25, in turn, engages with a gear 26- and pinion 27. Thepinion 27 engages the teeth 18 on the annular dial 17 and thus effectsthe drive thereof. The gear train including gears 23, 24, 24', 25, 25,26, 2'7, and 18 is of such nature that the dial 1'7 is rotated oncewhile the hand 22 is 93 rotated fourteen times. In this fashion, thedial 1'1 will be rotated once a week and the face thereof is dividedinto seven segments of equal length, designated by the days of the week,as illustrated in Figure 1. Each segment 95 is, in turn, divided intotwenty-four portions and suitably designated to indicate the hour of theday, as illustrated in Figure 1.

A plurality of operating lugs 28 are provided, the lugs beingconstructed preferably in accord- 10o ance with applicant's copendingapplication, above referred to, and certain of the lugs are formed toengage detent 16 to urge the same downwardly as viewed in Figure 1,while others are .formed to urgethe same upwardly. In this 106 fashion,the rotation of the annular dial 1"! is availed of to effect theoperation of lever 12 and arm 11. In the construction shown in Figure 1,the complete weekly cycle of operation is such that every week day apredetermined operation 110 is effected at 6 o'clock in the morning. OnMonday, Tuesday, Wednesday, Thursday and Friday, a reverse operation iseffected at 7 o'clock in the evening of these days while on Saturdaysuch operation is effected at 12 oclock noon. On Sunday in theconstruction illustrated in Figure 1 no operation is provided for.

Obviously, the device is of such character that the initial operationsof each day may be set for different times and the reverse operations atother times. Certain days may be omitted entirely and the operatingtimes of other days changed at will. In existing structures a weeklycycle has been possible only with a star wheel but in such constructionsa given. cycle of operations, once determined in the manufacture of thestar wheel, is repeated inflexibly and invariably.

If desired, the clock dial and hands may be omitted and an indicia or asuitable index mark applied to the stationary dial member to facilitatethe setting of the dial 17.

It will thus be seen that a completely flexible and eflective mechanismis provided for aii'ording a weekly cycle of predetermined character andwhile the invention has been described with specific reference to theaccompanying drawing, it is not to be limited, save as defined in theappended claim.

I claim as my invention:

A time switch mechanism, comprising a switch operating mechanism, a timeoperated mechanism, a stationary clock dial and hands driven by the timeoperated mechanism, an annular dial, means on the stationary dial tomount the annular dial thereon and concentric therewith to be rotatablewith respect thereto, said switch operating mechanism being disposedadjacent the periphery of the stationary and annular dials, a pluralityof sectors on the rotatable dial, means to drive the rotatable dial bythe time operated mechanism with a speed reduction over the hour handmotion of the time mechanism equal to a multiple of the num- 4 ber ofsectors on the rotatable dial, and adjustable switch operating lugs onthe rotatable dial.
